What is a roll bag? In short, the plastic bags are connected one by one, rolled up into a bundle, and gently pulled according to the cut gap when use, it is a bag, which is convenient for storage and use.
In the food section of supermarkets, we often see rolls of plastic bags. This is one of the common roll bags we make. In fact, there are many types of roll bags, which can be divided into flat-mouth bags according to different bag types. Rolled bags, vests with rolling bags, etc.; according to different functions, there are garbage bags with rolling bags, food bags with rolling bags, etc.; according to different printing, it can be divided into printed rolling bags and non-printed rolling bags.
In daily life, we can directly choose the continuous roll bag according to the purpose: one is food-grade material and the other is ordinary material. We must distinguish clearly when using it, and use it reasonably. How do we identify a good type of continuous roll bag? First of all, it can be distinguished from the appearance. Some roll bags are pure and transparent, with a smooth surface, smooth to the touch, and some are dark with a high degree of coverage, with a turbid and non-glossy surface, with a sticky and grainy feel. When choosing, it is necessary to choose different continuous roll bags according to different purposes: pure color, smooth surface, smooth hand feeling. The roll bags have better safety performance. The raw materials used in production are also pure raw materials imported from abroad, suitable for packaging. Food, grains, oils, rice noodles, etc. In contrast, the deep, opaque, and granular continuous roll bags are mostly made of recycled shopping bags, plastic bags, etc., and cannot be used as food packaging bags.
Secondly, it is judged by observing the burning material after burning. If the rolled bag is flammable and has a waxy smell during the burning process, and at the same time produces drop-like substances like candle oil, it is a good quality plastic bag. Containing waste or garbage plastic, suitable for food special purpose, healthy and safe, if it is not easy to burn, and if it emits pungent black smoke during the combustion process, it is an unqualified plastic bag, indicating that there is waste plastic and garbage plastic, and it is only suitable for packaging some courier and other items.
Finally, a careful friend will find that the roll-to-roll bags used in supermarkets are always transparent. That's because these bags are made of brand new materials, and the bags made of such materials are food-grade. In addition, in order to advertise, supermarkets always print advertisements on vest bags, and the advertising patterns contain ink. If they are used to hold food, it is definitely not possible. Therefore, there are always two kinds of bags in the supermarket, one is a transparent roll-on bag without advertising, and the other is an opaque t-shirt bag with advertising. Both are very important.
